Polymerisation

Polymerisation

1. Means loads of small molecules link together

   • Usually carbon based
   • Polymers are formed when under very high pressure small molecules join to form long chains

2. There are lots of different types of polymers

   • Strong rigid polymers used to make plastic milk bottles
   • PVC is strong so used to make window frames and piping, occasionally used to make synthetic leather

3. Polymers have replaced natural materials for some uses

   • Synthetic fibres [nylon, polyester] have replaced cotton + wool.
   • Rigid PVC replaced wood for window frames, its more water resistant
